Question

volume of cylinder is 4312 metre cube diameter is 28 find height TSA and csa​

Answer 1

Answer:

h = 7 m

T.S.A = 924 m^2

C.S.A = 616 m^2

Step-by-step explanation:

volume = 4312 m^3

diameter = 28 m

radius = 14 m

volume of cylinder = πr2h

4312 = 22/7 × 14 × 14 × h

h = 4312 × 7/ 22 × 14 × 14

h = 7 m.

T.S.A of cylinder = 2πr(r+h)

= 2 × 22/7 × 7 ×(7+14)

= 44× (21)

T.S.A of cylinder = 924 m^2.

C.S.A of cylinder = 2πrh

= 2 × 22/7 × 7 × 14

= 44 × 14

C.S.A of cylinder = 616 m^3.
